I’ve applied to renew my passport and one child; and applied for one first child. On the children’s applications I put the passport number from my expired passport (I just didn’t think at the time to put husband’s down which is still valid!). My adult renewal has now been approved and therefore given a new number. I’m now wondering whether there will be any issues with the child applications as the passport number I provided will now be incorrect/(old). Is the system clever enough to recognise that I did provide the passport number I had at the time and that it has just been changed or will it be a case of ‘computer says no’ as it doesnt now match up? Thank you in advance.
